I am going thru the same as you, I had the sleeve done 8yrs ago and before surgery I had very bad GERD I would wake up in the middle of the night choking on acid which I inhaled into my windpipe. But, After surgery it got better, but about 5 yrs later it started again, And that is when I found out that the sleeve actually promotes acid reflux. So 10 weeks ago I had the gastric bypass to help with reducing the acid producing cells in my stomach to find out that I have a moderately large hiatal hernia which I will possibly need another surgery to repair in the future. Right now omeprazole is helping. As I follow up with the doctor I will make updates.
